Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616708, here are decompositions:

31 + 31616677 = 31616708
37 + 31616671 = 31616708
61 + 31616647 = 31616708
139 + 31616569 = 31616708
199 + 31616509 = 31616708
229 + 31616479 = 31616708
307 + 31616401 = 31616708
349 + 31616359 = 31616708

Showing the first eight; more decompositions exist.
